Second hint for #5, and first hint for #4.
#5: The whole secret of the game is blatantly told on a mural halfway through the game, but when you first play it, you don't exactly realise what it means until the end boss explains it.
Hint 2: The mural was pretty vague about it, but the boss explains that beating him, would wake another entity and have far-reaching consequences for the land you're in and everyone that inhabits it.
#4: This game features the most annoying sound in the world. Guessed by drbunnig - Super Mario World 2: Yoshi’s Island
